For practice tried to make a brush that shows a starry shape after some interval. It looks a bit like barbed wire.
Short explanation in case anyone is interested:
The star shape is made by showing y-scaled circles randomly at exactly 5 different angles. The angles are made by multiplying a random signal by 5, then flooring it to get an integer interval [0,5], then dividing by 5 again to get [0, 0.2, 0.4, .., 1] (Does anyone know a better way to get this btw?
) This is fed to the rotation parameter.
The interval is decided by modulating the length, and only showing the y-scaling for a short while when the value is close to 0.
